First of all, introduce pencils to beginners: art pencils have lead cores of different grades.
Hard ones are represented by "h", such as: 1H, 2H, 3H, 4H, etc. The greater the front number, the stronger the hardness, that is, the lighter the chromaticity;
Soft ones are indicated by "b", such as 1B, 2B, 3B, 4B, 5B, 6B, etc. The larger the number, the stronger the softness and the darker the chroma.
The first step is to draw the teacher's 6B above 2B with soft lead. First, draw the outline, the dividing line between light and shade and the pattern of fixed-point projection, and draw the big interlining.
Step 2, lay a major, and use a pencil of 6B or 8B to find the darkest place in the picture, that is, the dark side projection of the fruit and the projection line of the interlining. Pay attention to the strength of the wrist.
Such a step diagram should be very detailed.
Step 3: unify the dark side with a pen and paper, continue to draw the dividing line between light and dark with a pencil, pay attention to the gray side of the reflective picture, draw short lines with a pencil of 2B or HB, and gently wipe the highlights of the picture with a pen and paper to shape an object.
Fourthly, forming the interlining.
Many students can't draw interlining well. Why is this? Recording women's songs changes instantly? What does your mother do? Why did you send me for a change? The basic geometric knowledge of sketch such as cube, cylinder and sphere is applied to drawing interlining. Because interlining is also a "still life", as long as you understand the basic modeling rules of sketch, interlining is not difficult to express.
From the beginning, we made the interlining plan. After that, we should first deal with the three relationships of bright surface, gray surface and dark surface, and then draw more rich levels of light and shade, which is what we usually call "three sides and five tones" We should also pay attention to the relationship between reality and reality.
